Path of Exile Item Upgrading
The ability to upgrade item level upgrade (mozillabd.science) items allows players to upgrade their weapons and gear with new affixes, boosting the base stats of the item upgrader or giving additional benefits. To upgrade an item upgrader mod, the player has to have it in their inventory and have access to the kiln.
Items with weak bases, like rings can be upgraded to stronger bases. Items with strong bases, like the Titans of eth have little change in their stats.
Upgrade components
Upgrade components can be used to upgrade items trinkets, armor, weapons and tools for gathering, offering an added bonus or effect when the equipment is in use. They can be purchased from vendors, gathered in loot, dropped by enemies, or obtained as a reward from missions or chests. Certain upgrades come with additional cosmetic effects. Most upgrades require that the equipment be above a certain level before they can be upgraded.
